Processes to make alkylate gasoline by sulfur-contaminated ionic liquid catalyzed alkylation
Processes are provided for making an alkylate gasoline blending component, comprising: a. feeding an olefin feed comprising greater than 80 wppm of a sulfur contaminant comprising mercaptans, alkyl sulfides, and alkyl disulfides to a chloroaluminate ionic liquid catalyst, wherein a level of the sulfur contaminant accumulates in the chloroaluminate ionic liquid catalyst to make a sulfur-contaminated ionic liquid catalyst comprising 300 to 20,000 wppm of a sulfur; and b. alkylating the olefin feed with an isoparaffin using the sulfur-contaminated ionic liquid catalyst to make the alkylate gasoline blending component having a final boiling point below 221? C. An alkylation process exclusively utilizing coker LPG olefins is also provided.
Catalysts for oxidative sulfur removal and methods of making and using thereof
Catalysts for oxidative sulfur removal and methods of making and using thereof are described herein. The catalysts contain one or more reactive metal salts dispersed on one or more substrates. Suitable reactive metal salts include those salts containing multivariable metals having variable valence or oxidation states and having catalytic activity with sulfur compounds present in gaseous fuel streams. In some embodiments, the catalyst contains one or more compounds that function as an oxygen sponge under the reaction conditions for oxidative sulfur removal. The catalysts can be used to oxidatively remove sulfur-containing compounds from fuel streams, particularly gaseous fuel streams having high sulfur content. Due to the reduced catalyst cost, anticipated long catalyst life and reduced adsorbent consumption, the catalysts described herein are expected to provide a 20-60% reduction in annual desulfurization cost for biogas with sulfur contents ranges from 1000-5000 ppmv compared with the best adsorbent approach.
